• dojo dynamic right click context menu

  - by levy

  There are tons of different dojo right click context menus in a page slowing down the browser. Some divs have context menus while some others don't. So I just can't have a dynamic global context menu and still be able to fallback to the browser's built in menu in some cases, do I? The non lazy instantiation of the dojo context menus just take too much time. How can I make those context menus dynamic? Preferably being created on demand when the user actually right clicks on them.

• Gtk_entry mouse click signal

  - by h4rp0

  Hi, I want to do a g_signal_connect to capture a mouse click in a gtk_entry widget. Something like this: entry = gtk_entry_new ( ); gtk_box_pack_end ( GTK_BOX ( hBox ), entry, TRUE, TRUE, 1 ); gtk_widget_show ( entry ); // This is the one I'm not sure about g_signal_connect ( GTK_OBJECT ( entry ), "????????????", GTK_SIGNAL_FUNC ( EntryClicked ), entry ); I just can't seem to find it in the gtk documentation. I've tried using the "focus-in-event", but it is not working as I spect. Thanks for the assistance.

• selecting all text within a div on a single left click with javascript

  - by tstyle

  I have a simple non-clickable link within a div that looks like this: It's meant to be a sharable link that the user can copy paste into other things. For usability purposes, I want a single left click anywhere within the div to select the entire link: I don't know much about, javascript/web programming, so I've tried the following: <div id="share_link" onClick="select_all('share_link')"><%= request.url %></div> and this javascript <script type="text/javascript"> function select_all(id) { document.getElementById(id).focus(); } </script> This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

• iOS Display Different Image on Click

  - by user1506841

  Using XCode, I am trying to figure out how to display a different image when someone clicks or presses down on one of my buttons before being taken to a second screen. For example, I have a contact icon on my home screen. When a user clicks the icon, it should change to a darker version on tap before going to the contact screen. Any help is appreciated. -(IBAction) ButtonPressed :(id)sender { UIButton *tempButton = (UIButton *) sender; int tag = tempButton.tag; NSString *viewName; switch (tag) { case 1: [FlurryAnalytics logEvent:@"Contact-Screen"]; viewName = @"ContactScreen"; if( self.appDelegate.sound) [Click play]; [self.appDelegate moveToView:viewName]; break; } }

• How to Export Multiple Contacts in Outlook 2013 to Multiple vCards or a Single vCard

  - by Lori Kaufman

  We’ve shown you how to export a contact to and import a contact from a vCard (.vcf) file. However, what if you want to export multiple contacts at the same time to multiple vCard files or even a single vCard file? Outlook doesn’t allow you to directly export all your contacts as vCard files or as a single vCard file, but there is a way to accomplish both tasks. Export Multiple Contacts to Multiple vCard Files Outlook allows you to forward contact information as a vCard. You can also select multiple contacts and forward them all at once. This feature allows you to indirectly export multiple contacts at once to multiple vCard files. Click the People tab to access your contacts. Select all the contacts you want to export using the Shift and Ctrl keys as needed. Select Contacts the same way you would select files in Windows Explorer. Click Forward Contact in the Share section on the Home tab and select As a Business Card from the drop-down menu. The selected contacts attached to a new email message as .vcf files. To select all the attached .vcf files, right-click in the Attached box and select Select All from the popup menu. Make sure the folder to which you want to export the contacts is open in Windows Explorer. Drag the selected attached .vcf files from the new email message to the open folder in Windows Explorer. A .vcf file is created for each contact you selected and dragged to the folder. You can close the Message window by clicking on the X in the upper, right corner of the window. NOTE: You can also close the Message window by clicking the File tab. Then, click the Close option on the left. Because you already have your .vcf files, you don’t need to save or send the message, so click No when asked if you want to save your changes. If it turns out that a draft of your message was saved, the following message displays. Click No to delete the draft. Export Multiple Contacts to a Single vCard (.vcf) File If you would rather export your contacts to a single vCard (.vcf) File, there is a way to do this using Gmail. We’ll export the contacts from Outlook as a .csv file and then use Gmail to convert the .csv file to a .vcf file. Select the contacts you want to export on the People page and click the File tab. On the Account Information screen, click Open & Export in the list on the left. On the Open screen, click Import/Export. The Import and Export Wizard displays. Select Export to a file from the Choose an action to perform list and click Next. In the Create a file of type box, select Comma Separated Values. Click Next. Contacts should be already selected in the Select folder to export from box. If not, select it. Click Next. Click Browse to the right of the Save exported file as box. Navigate to the folder to which you want to export the .csv file. Enter a name for the file in the File name edit box, keeping the .csv extension. The path you selected is entered into the Save exported file as edit box. Click Next. The final screen of the Export to a File dialog box displays listing the action to be performed. Click Finish to begin the export process. Once the export process is finished, you will see the .csv file in the folder in Windows Explorer. Now, we will import the .csv file into Gmail. Go to Gmail and sign in to your account. Click Gmal in the upper, left corner of the main page and select Contacts from the drop-down menu. On the Contacts page, click More above your list of contacts and select Import from the drop-down menu. Click Browse on the Import contacts dialog box that displays. Navigate to the folder in which you saved the .csv file and select the file. Click Open. Click Import on the Import contacts dialog box. A screen displays listing the contacts you imported, but not yet merged into your main Gmail contacts list. Select the contacts you imported. NOTE: The contacts you imported may be the only contacts in this list. If that’s the case, they all should be automatically selected. Click More and select Export from the drop-down menu. On the Export contacts dialog box, select Selected contacts to indicate which contacts you want to export. NOTE: We could have selected The group Imported 10/10/13 because that contains the same two contacts as the Selected contacts. Select vCard format for the export format. Click Export. Gmail creates a contacts.vcf file containing the selected contacts and asks you whether you want to open the file with Outlook or save the file. To save the file, select the Save File option and click OK. Navigate to the folder in which you want to save the contacts.vcf file, change the name of the file in the File name edit box, if desired, and click Save. The .vcf file is saved to the selected directory and contains all the contacts you exported from Outlook. This could be used as a way to backup your contacts in one file. You could also backup the .csv file. However, if you have a lot of contacts you will probably find that the .vcf file is smaller. We only exported two contacts, and our .csv file was 2 KB, while the .vcf file was 1 KB. We will be showing you how to import multiple contacts from a single .vcf file into Outlook soon.

• Handling 2 buttons submit Actions in a single View/Form - ASP.NET MVC 2 RTM

  - by Leniel Macaferi

  I have a View in which the user is able to upload a file to the server. In this view I also have 2 buttons: one to Upload a file and other to Download the last file imported. In my Controller I created 2 action methods: Import and Export. How could I manage to redirect each button click to the proper action method in my Controller? I have tried Html.ActionLink: <%= Html.ActionLink("Upload", "Import", "OracleFile")%> <%= Html.ActionLink("Download", "Export", "OracleFile")%> Html.ActionLink didn't do the trick. The action links were taking me to the right Action methods but they were generating a GET request. This way Request.Files.Count = 0. I need a POST request. Note: the most intriguing part is that the upload was working and all of sudden it stopped working. I've seen that some people are having the same problem with FileUpload tasks in which the Request.Files is always Empty. I think it's empty because you need a post to the server. Isn't it?

• iPhone: CATiledLayer/UIScrollView wont scroll after zooming and only zooms to anchor point

  - by Brodie4598

  Here is the problem... I am using CA Tiled Layer to display a large jpg. The view loads okay, and when I go to scroll around, it works fine. However, as soon as I zoom in or out once, it scrolls to the top left (to the anchor point) and will not scroll at all. The zooming works fine, but I just cannot scroll. Here is my code: #import <QuartzCore/QuartzCore.h> #import "PracticeViewController.h" @implementation practiceViewController //@synthesize image; - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect pageRect = CGRectMake(0, 0, image.size.width, image.size.height); CATiledLayer *tiledLayer = [CATiledLayer layer]; tiledLayer.anchorPoint = CGPointMake(0.0f, 1.0f); tiledLayer.delegate = self; tiledLayer.tileSize = CGSizeMake(1000, 1000); tiledLayer.levelsOfDetail = 6; tiledLayer.levelsOfDetailBias = 0; tiledLayer.bounds = pageRect; tiledLayer.transform = CATransform3DMakeScale(1.0f, -1.0f, 0.3f); myContentView = [[UIView alloc] initWithFrame:self.view.bounds]; [myContentView.layer addSublayer:tiledLayer]; UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds]; scrollView.delegate = self; scrollView.contentSize = pageRect.size; scrollView.minimumZoomScale = .2; scrollView.maximumZoomScale = 1; [scrollView addSubview:myContentView]; [self.view addSubview:scrollView]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myContentView; } - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx { NSString *path = [[NSBundle mainBundle] pathForResource:@"H-5" ofType:@"jpg"]; NSData *data = [NSData dataWithContentsOfFile:path]; image = [UIImage imageWithData:data]; CGRect imageRect = CGRectMake (0.0, 0.0, image.size.width, image.size.height); CGContextDrawImage (ctx, imageRect, [image CGImage]); } @end

• Detect click on URL in RichEdit

  - by Tofig Hasanov

  I am trying to update RichEdit so that it detects URL and enables clicking on it to open in the browser. Detecting URL is easy, I just use the following code from http://www.scalabium.com/faq/dct0146.htm mask := SendMessage(MNote.Handle, EM_GETEVENTMASK, 0, 0); SendMessage(MNote.Handle, EM_SETEVENTMASK, 0, mask or ENM_LINK); SendMessage(MNote.Handle, EM_AUTOURLDETECT, Integer(True), 0); but the second part doesn't work for me. They give the following code to capture EN_LINK message and processing it: type TForm1 = class(TForm) protected procedure WndProc(var Message: TMessage); override; end; ... procedure TForm1.WndProc(var Message: TMessage); var p: TENLink; strURL: string; begin if (Message.Msg = WM_NOTIFY) then begin if (PNMHDR(Message.LParam).code = EN_LINK) then begin p := TENLink(Pointer(TWMNotify(Message).NMHdr)^); if (p.msg = WM_LBUTTONDOWN) then begin SendMessage(RichEdit1.Handle, EM_EXSETSEL, 0, LongInt(@(p.chrg))); strURL := RichEdit1.SelText; ShellExecute(Handle, 'open', PChar(strURL), 0, 0, SW_SHOWNORMAL); end end end; inherited; end; When I run the program, URL is detected, but clicking on it doesn't do anything. Using debug I found out that Message.Msg = WM_NOTIFY is not true when I click on URL. I then tried to override TRichEdit's WndProc, but result is the same. Any suggestions?

• jQuery Validation Plugin: Invoke errorPlacement function when onfocusout, keyup and click

  - by th3hamburgler

  Hi, I am using the jquery validation plugin and want to use the errorPlacement function to add error messages to the fields title attribute and display just a ? next to the field. This works great when the form is submitted with the submit button but when any of the following events are triggered: - onfocusout - click - onkeyup The validation checks are run but it skips the errorPlacement function and adds the full error message after the field, like the default behaviour. I am using the following code: $("#send-mail").validate({ debug: true, // set this class to error-labels to indicate valid fields success: function(label) { // set text as tick label.html("&#10004;").addClass("valid"); }, // the errorPlacement has to take the table layout into account errorPlacement: function(error, element) { console.log("errorPlacement called for "+element.attr("name")+" field"); // check for blank/success error if(error.text() == "") { // remove field title/error message from element element.attr("title", ""); console.log("error check passed"); } else { // get error message var message = error.text(); // set as element title element.attr("title", message); // clear error html and add cross glyph error.html("&#10008;"); console.log("error check failed: "+message); } // add error label after form element error.insertAfter(element); }, ignoreTitle: true, errorClass: "invalid" });

• JAVASCRIPT changing on click

• jquery add to an array on click?

  - by KittyYoung

  I'm confused regarding each() and .each()... I think I need to use both, but I'm not sure how... Basically, I have a series of checkboxes and when they're checked, I want to get the id of the closest table row and add it to an array that I can then serialize and pass to a function. So, the html looks like this: <tr id="t1"><td><input type="checkbox" name="did[]" value="232" class="bd" /></td></tr> <tr id="t2"><td><input type="checkbox" name="did[]" value="234" class="bd" /></td></tr> <tr id="t3"><td><input type="checkbox" name="did[]" value="676" class="bd" /></td></tr> <tr><td><button id="tsid" name="tsid" type="button">Send</button></td></tr> And, when (and if) the checkbox is selected, I want to get the closest tr id and store it in an array: var trids = [] And then serialize the input data and the trids array... So far, I only have this: $('#tsid').click(function() { //meant to get the values of the selected checkboxes var myData = $('input[name=did[]]').serialize(); //meant to find and store the closest tr ids in an array... $('.bd').each(function() { var trids = $(this).closest("tr").get(0); //and now I'm lost... }); }

• Switching from Java to .NET from a career change point of view

  - by Joe

  Could anyone share with me their experience with switching from Java to .NET from a career point of view? I've been a Java developer for 12 years and am just getting tired of how fragmented the Java world has become. For my liking, there's just too many frameworks, tools, application servers, etc.. And it seems each new tool just adds complexity and time to even the simplest of projects. I'm not trying to start any wars - I'm just giving you the reason I ask the main question. I've read a few books on .NET and have done one WebForms job. I love the integrated environment and would like to hear how others transitioned from Java to .NET. What I mean by that is did you do it somehow as a contractor or did you join a company as a beginner .NET developer with much Java experience? Personally, I'm ready to take the leap if I can figure out how to not lose too much income in the process (Senior Java developer to beginner .NET developer). I would really appreciate hearing your stories.

• Appending html data when item in html select list is selected

  - by Workoholic

  I have a selector that could look like this: <label for="testselector">Test</label><br /> <select id="testselector" name="test[]" size="5" multiple="multiple"> <option name="test_1" value="1">Test Entry X</option> <option name="test_3" value="2">Test Entry Y</option> <option name="test_5" value="5">Test Entry Z</option> </select> <div id="fieldcontainer"></div> When an entry from the above fields is selected, I want two form fields to appear. I use jquery to add them: $("#fieldcontainer").append("<div><label for=\"testurl\">Test Url</label><br /><input name=\"testurl[]\" type=\"text\" id=\"testurl_1\" value=\"\" /></div>"); $("#fieldcontainer").append("<div><label for=\"testpath\">Test Path</label><br /><input name=\"testpath[]\" type=\"text\" id=\"testpath_1\" value=\"\" /></div>"); I can easily add a click handler to make those form fields appear. But how would I keep track of what form fields were already added? When multiple fields are selected, the appropriate number of input fields needs to be added to the fieldcontainer div. And if they are unselected, the input fields need to be removed again. I also need to retrieve the value from the options in the select list to add them as identifier in the added input fields...

• Problems with registering click event listener to a frame-element

  - by distractedBySquirrels

  Hi everybody, I ran into a problem with adding an event listener. I wrote a Firefox plugin a while ago for my bachelor thesis. It was based on a different attacker model than you would normally expect. In this scenario the attacker was the service provider (like Facebook, Google,...), who reads all your private data stored on their site (via JS). My final solution was to temporally allow JS (while the page loads and after an user action occured). To observe the interaction I used event listener, which worked very well so far. But last week I noticed that my approach doesn't work with web sites which are using a frameset (I added the event listener to the body...). So I tried to add the listener to the frameset respectively to the frame. But the clicks are only noticed when you actually click on the frame... (eg resize the frame with your mouse) But I want to register clicks on the document loaded inside the frame. I already tried the .frameElement. Sadly it seems that Firefox doesn't like my (or, which is more likely, I'm too stuipd :) ) and claims there are no frames... Could anyone tell me how to add an event listener to the document inside a frame? The web site looks like this: <html> <head> <title>Frameset Test</title> </head> <frameset cols="150,*"> <frame src="nav.html" name="Navigation"> <frame src="main.html" name="Main"> </frameset> </html> This was my first bigger projekt with Mozilla so this could be a really dumb failure of mine... I hope you guys can help me. Thanks in advance. Sebastian
